Donnie's negotiation with William Mellon lasted until the following morning before a formal outcome was reached.
First, if Pandora Oil Company truly manages to acquire Sinclair Oil Corporation in the future, then Mellon Bank will need to repay the eight million US Dollar loan interest to Donnie Block.
Second, if the acquisition is completed, then Donnie's Pandora Oil, Sinclair Oil and William Mellon's Gulf Oil will undergo a stock swap. Donnie will be in charge of both Pandora Oil and Sinclair Oil, while William Mellon will still control Gulf Oil, but both parties must agree that if either side wants to give up their current oil company in the future, they can only sell their shares to the other at the current market price.
